1.1 Scope. 1.1.1 This standard shall establish the minimum requirements for the design, performance, testing, documentation, and certification of protective ensembles and ensemble elements for protection from chemicals, biological agents, and radiological particulates (CBRN) terrorism agents. 1.1.2* This standard shall establish requirements for protective ensembles and ensemble elements that are worn for a single exposure at incidents involving CBRN terrorism agents. 1.1.3 This standard shall establish requirements for new CBRN protective ensembles and ensemble elements. 1.1.4* This standard shall not establish requirements for respiratory protection for incidents involving CBRN terrorism agents. Appropriate respiratory protection for the incidents involving specific CBRN terrorism agent exposure is a critical part of overall protection and shall be specified and provided by the authority having jurisdiction. 1.1.5 This standard shall not establish requirements for any fire-fighting applications. 1.1.6* This standard shall not establish requirements for protection at incidents involving ionizing radiation, liquefied gas, cryogenic liquid hazards, explosives, or explosive atmospheres. 1.1.7* CBRN protective ensembles and ensemble elements that are certified as compliant with NFPA1994 shall be permitted also to be certified to NFPA1991, Standard on Vapor-Protective Ensembles for Hazardous Materials Emergencies, NFPA1992, Standard on Liquid Splash-Protective Ensembles and Clothing for Hazardous Materials Emergencies, and the single-use requirements of NFPA 1999, Standard on Protective Clothing for Emergency Medical Operations. 1.1.8 This standard shall not apply to any accessories that could be attached to the certified product, before or after purchase, but are not necessary for the certified product to meet the requirements of this standard. 1.1.9 This standard shall not be construed as addressing all of the safety concerns associated with the use of compliant CBRN protective ensembles and ensemble elements. It shall be the responsibility of the persons and organizations that use compliant CBRN protective ensembles and ensemble elements to establish safety and health practices and determine the applicability of regulatory limitations prior to use. 1.1.10 This standard shall not be construed as addressing all of the safety concerns, if any, associated with the use of this standard by testing facilities. It shall be the responsibility of the persons and organizations that use this standard to conduct testing of CBRN protective ensembles and ensemble elements to establish safety and health practices and determine the applicability of regulatory limitations prior to using this standard for any designing, manufacturing, and testing. 1.1.11 Nothing herein shall restrict any jurisdiction or manufacturer from exceeding these minimum requirements.
